Abstract

A ceiling fan includes a drive motor having a first web rotatably mounted relative to a mounting boss securing the drive motor. A second web is mounted in a parallel spaced relationship below the first web in a coaxially aligned relationship relative to the drive motor and mounting boss. A plurality of blade loops are directed from the first web to the second web, wherein each blade loop includes an upper blade and lower blade of a predetermined pitch to effect displacement of air within a predetermined environment.

Claims

exact text as granted — not AI-modified
What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows: 
     
       1. A ceiling fan and blade assembly, comprising, a drive motor, the drive motor having a mounting boss, and   an illumination lens housing mounted to the drive motor below the mounting boss, wherein the illumination housing, the mounting boss, the drive motor are coaxially aligned about a predetermined axis, with an illumination bulb mounted within the illumination housing, and   the drive motor having a first web, and   the first web orthogonally oriented to and medially intersected by the predetermined axis, and   a second web oriented below in a parallel spaced relationship relative to the first web, and   blade members mounted to the first web and the second web, and   the blade members include individual fan blade loops, wherein each fan blade loop of said fan blade loops extends from the first web to the second web, with each fan blade loop having a planar upper blade loop and a planar lower blade loop, with the planar upper blade loop and the planar lower blade loop oriented relative to one another having an acute included angle therebetween, with an arcuate transition web fixedly mounting the upper blade loop to the lower blade loop.   
     
     
       2. A ceiling fan and blade assembly as set forth in claim 1 wherein each of the fan blade loops are transparent. 
     
     
       3. A ceiling fan and blade assembly as set forth in claim 2 comprising a plurality of blade members including individual fan blade loops, wherein each fan blade loop of said fan blade loops is arranged relative to a central web, wherein each fan blade loop is mounted to the central web, and each fan blade loop includes a planar upper blade loop and a planar lower blade loop, with the planar upper blade loop and the planar lower blade loop oriented relative to one another, and an arcuate transition web fixedly mounted to the upper blade loop and the lower blade loop spaced from the central web.
